So what your saying is that it just has to be larger than the original image. So I can draw one side of the image 2 times and the other side 2.5 times. I thought everything had to be in the correct proportion???

larger or smaller is specified in the ques..usually its larger..

n u cant draw 2 halves of different proportions..either draw the whole image 2x or 2.5x

TheMysteriouseDude I need your advice on how to study for the in depth and which areas to concentrate on more, By the way what do you predict will come for in depth? (Hope asking predictions is not against the rules)

Does anybody know what we should focus on for maths paper 2 and maths paper4?

I mean what mostly comes in paper 2? and what mostly comes in paper 4? Im saying this because i dont want to waste my time studying everything when someone else knows what paper 2 mostly focuses on and what paper 4 mostly focuses on.

the topics r not divided for p2 and p4
all topics can come in any paper

though if u get suppose circle theorems in one paper, it may not come in the other paper
but again, no guarantee

Guys, concerning physics, if the voltage is equal to 12, and resistance is 0, what is the current?

this ain't possible...

You cannot produced a potential difference without resistance. voltage drop across any uninterrupted length of wire in a circuit where wire is assumed to have zero resistance will always be zero, no matter what the magnitude of current, since zero multiplied by anything equals zero.


Hope that helps

but, logically, if there is no resistance, the current is supposed 2 be high isnt it?

now there is nothing that offers 0 resistance point 1. If it does, it doesn't matter if the current is high....voltage will still be 0

and if yu dont mind, can yu clear my doubts about the ray diagrams and thermal expansions in the 'All Physics Doubts Here' board? Thank You

so yu say its all about the usage of the formula only right? -V=IR-

yes the formula.

I will check the other thread
